CORRECTION :
After posting the previous message, I went back to double-check my facts.
I should have done it before, because I was wrong. There is a very specific
NOTAM, published 6 May that details several Temporary Restricted Areas and a
few Temporary Prohibited Areas. There are rules for avoidance, and even rules
for interception if one is found in the wrong place at the wrong time. It
doesn't say they'll shoot you down, of course, but it does strongly imply that
it's in your interest to comply meticulously. They also say infractions could
be fined 15000 to 45000 Euros and up to six months in jail, plus impounding
the aircraft.

I have mentioned to several pilots over the past days that I was surprised not
to see any NOTAMS for those days - They must have been shaking their heads
thinking "What's this poor fool on about . . ."

Anyway, my apologies for the incorrect information.
For any who want to see the NOTAM, it's here :
